Yes I did think of that. They have 10 more opportunities. Items sold 16th August, so another week. Hopefully he won't think of it. If it happens I will try and deal with it again. As I said, it is the only Feedback he has ever left (on this ID) and he has literally 100s and 100s  of purchases. I assume it is because he has found I have blocked him - some sellers have said very nasty (but no doubt true) things  in Feedback and he has never bothered to have them removed, though he certainly could, as they break all the rules about Sellers leaving false positives.
